Light-driven conductivity control for quantum nanoscale data processing.

Researchers have proposed a theoretical framework that uses quantum electrodynamics coupled with Floquet engineering to enhance the propagation length of surface plasmon polariton (SPP) modes. By modifying the electrical and optical characteristics of metal nanostructures within plasmonic waveguides, it is possible to enhance SPP propagation lengths significantly. The plasmonic and conductive properties of popular plasmonic metals, including silver, gold, copper, and aluminum, were analyzed under the illumination of a particular form of light using computer simulation based on code specifically written to explore this novel observation. This discovery could lead to the development of efficient and advanced nanoscale plasmonic data processing devices, circuits, and components in the near future.
